Currently, when updating section permissions to mark areas ROor NX, the only mm updated is current->mm. This is working offthe assumption that there are no additional mm structures atthe time. This may not always hold true. (Example: callingmodprobe early will trigger a fork/exec). Ensure all mm structresget updated with the new section information.

Signed-off-by: Laura Abbott <labbott@fedoraproject.org>---I don't think we can get away from updating the sections if the initmem isgoing to be freed back to the buddy allocator. I think this should covereverything based on my understanding but my knowledge may be incomplete.--- arch/arm/mm/init.c | 92 ++++++++++++++++++++++++++++++++++++------------------ 1 file changed, 62 insertions(+), 30 deletions(-)
